CHARLES S. EMMERT, OF CHICAGO, ILLINOIS.

BINDING-MACHINE.

Specification of Letters Patent.

Application filed May 31, 1911.

a citizen of the United States, and a resident of Chicago, in the countyof Cook and State of Illinois, have invented certaln new and -usefulImprovements in Binding-Machines; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this specification.

This invention relates to an improvement in binding machines adapted tobend a length of wire about a member to be bound, as for example, apiece of cotton warp, a

rope end, or the like, and consists of thematters hereinafter describedand more particularly pointed out in the appended claims.

The improved machine is particularly adapted for making daubers of thekind used with shoe polish and the like consisting of a short length ofcotton warp bound by a part of a length of wire, the other part of whichconstitutes the handle for the dauber or the member for attaching saiddauber to the cork of the bottle containing the polish, in which casesaid cork is used as the handle for the dauber.

In the drawings: Figure l is a view representing a front elevation of myimproved machine showing the binding wire in position ready to be boundabout the cotton warp; Fig. 2 is a. view representing a like frontelevation of the machine with the parts thereof in their relativepositions as they appear after the machine has been operated.

to bind the wire about the warp; Fig. 3 is a View representing a sectionthrough the machine in a plane indicated by the line 33 of Fig. 1; Fig.4 is a View representing a top plan View of the machine with the partsin the relative positions shown in Fig. 2; Fig. 5 is a perspective viewshowing the end of the tube through which the cotton warp is fed.

Referring now to that embodiment of my invention illustrated in thedrawings, 10 indioates a plate which carries the operating parts of themachine and'which is supported preferably in an upright position by anyconvenient means (not shown). Said plate has a slot 11 extending fromits upper edge downwardly and intermediate the ends of said slot anopening 12 is formed in the plate into which opening extends a circulartube 13 which is adapted for the feed of the cotton warp to the binder.divides the upper end of said plate intoparts 10, 10", which are adaptedto be clamped against said tube by means of a long bolt 14 extendingloosely through an aperture in the part 10 of the table andbeingthreaded into the part 10 Said bolt has a head 14: adapted forengagement against the vertical edge 10. of the part 10 of the plate 10.The end of the tube 18 projects forwardly beyond the front face of theplate 10 and said tube is preferabl' tapered toward its front end (see Fi'g. 3, in order that the strands of the cbtt rn -v ax'p may be drawnmore closely togetheras they approach the front end of the tube justbeyond which the binding wire is applied.

On the front projecting end of the tube 13 is rotatively mounted acarrier, in this case a gear 15 having on its rear face a'boss 13 whichengages against the front face of the plate 10 while its peripheralmargin, offset from the plate 10 by said boss, extends into verticalgrooves 16 17*, in 0ppositely disposed plates 16, 17, which are boltedto the front face of the said plate 10.' A

vertically reciprocable rack 18 is mounted in the groove 16 of the plate16 with its teeth engaged with the teeth of the gear 15. A link 19 ispivotally connected to the lower end of the rack-bar l8 and may beconnected to any suitable operating member, as for example, a foottreadle- (not shown). A- stop 20 secured to the front face of the rackbar in position for engagement with the lower edge of the plate 16, actsto limit the upward movement of the rack-bar, and a coiled spring 21attached at its lower end to a lateral projection 20 of the rack bar andat its upper end to a lug or pin 22 connected to the plate 10 normallyholds the rack-bar in its uppermost position.

The front end of the tube 13 has its surface shaped to conform to aconvolution of a helical curve the pitch of which is substantially equalto the diameter of the wire that is used to bind the strands of thecotton warp together. The convolution of the helix terminates in alongitudinal shoulder 13 and a notch 13 is cut in the end of said tubein advance of saidshoulder 13", saidnotch being adapted for thereception of the] end of the wire binder.

23 indicates a binder member WlllCll, as shown herein, consists of aroller rotatively The said slot' 13, that its peripheral bearing surfaceis spaced from the tube 13 a distance equal to 'the diameter of thebinder wire. The said roller has a radial flange 24 which is located ina vertical plane and is spaced from the vertical plane extending throughthat part "of the tube end which projects farthest a distance equal tothe diameter of the binding wire.

The operation of the machine'is as follows: A length of'wire 25,preferably pro-' videdwith a sharpened end 25? is inserted through .thenotch 13 at the front end of the tube 13 into the cotton warp or othermember to be bound, which has first been drawn through the tube 13 untilits end projects beyond the forward end of said tube,

the required distance. The length of wire is then bent at right anglesto the pointed end 25* either by a hammer or in any other way. It ispreferable to form this bend in the first instance before the end of thewire is inserted into the warp. In the normal position of the parts ofthe machine the binder or roller 23 is to the right of the notch 13 ofthe tube 13, as shown in Fig. 1, while the length of binder wire 25eiztends to the left thereof, that is to say,.the binder is located onthe side of the notch which is opposite to the side on which said wire25 is located. The rack-bar 18'is now depressed by the treadle or otheroperating member, rotative move ment in the direction of the arrow beingthus imparted to the gear 15. This movement of the gear revolves thehinder or roller 23 in a circular path aboutthe tube 13, said movementbeing continued perferably through a little more than 360 of are, sothat said binder twice passes-the notch 13 in the end of the tube. Inthis movement the hinder or roller 23 engages the Wire 25 and carries itaround with it. In this action of the binder it first bends the wire 25against the shoulder l3 causing said wire to assume the position of achord to the other circumference of the tube 13 so that it engagesagainst the outer peripheral surface of the cotton warp. The continuedmovement of said binder about the tube swings the Wire with it and bendssaid wire about the cotton warp. At the same time the helical endsurface 13 of the tube 13 properly guides the wire so that when it hasbeen swung into a horizontal position again as shown in Fig. 2, it willlieclosely adjacent to that part of its length forming the beginning ofthe bend, being held in said position by the radial flange 24 ofthe-binder 23 which coacts with the end of the tube 13 to bring theparts into this relation. The machine thus causes the wire to make alittle more than one complete turn or convolution of a helical coilabout the cotton warp. The extra length of wire may then be cut off, orin the case of the manufacture, of daubers of the class described,

the extra length may be used as part of the.

handle for the dauber, and the cotton warp drawn beyond the end of thetube and severed at a point spaced from the wire binder, in which casethe severed piece of cotton warp will be attached to a length of wirewhich is bound about it intermediate of its ends.
